Its is based on the layout/PCB design. No strip is all in series, typically they are laid for voltage ie 8 leds in S will be say 24v, you would then parallel all those strings up so that the current is then divided by the n(number) of parallel strings. So below is our 98CRI 2 ft strip, it runs...

Most leds, for marketing are characterised at 70CRI as this is the most efficient version of the led. The issue is that this is a power led vs midpower, so typically 350ma rating vs 65ma, respectively. That not to say that at 65ma the power led will not match the midpower but in that comparison...

calling it a horticultural led by just having ppf data etc, dont make it so

its doable. when hot the strips at 700ma will function around 18v, and they will get hot, so wire up two in series 18x2=36v, and then run out parallel strings. I would build 4 parallel, so total 8 strips, if you were starting from scratch look for better strip/driver match. Cheers Mark

cri as such is more a metric for the architect when wanting light to match an illuminant base, its role in grow lights as a metric is not fully recognised, that is to say, CRI reflects an attempt to match 100 which is sunlight. Logically a light source that matches the sun would in fact be...

To have a whole grow cycle resting on a 50c dimmer seems kinda silly cheers

sadly the race to the bottom on price of lights means cutting corners, chinese POTS are piss poor and a common failure cheers

the kit says Epistar on the mono's, thats light speak for mid power, not high power reds used on higher priced boards, thats why they are cheap Cheers Mark

if it lights, then likely the driver still functions, most likely the dimmers, take them out of circuit and see if it full powers, if not, then possibly the driver does have some issue, although two failing together, seems hard to see it Cheers

If you want to have a conversation about penetration you need to hear from the side lighters, is this by definition penetration?. I hear everything from 0 to 40% improvement in outcomes with side lights but dependent on grow methods

super valid point, this highlights the differences of a nuanced approach to spectrum, lost on newbies and to some extent irrelevant if you dont have the experience, you will get that in time, but it seems to me that mixing CCT and promoting it as different/better is smoke and mirrors and likely...

Rocket makes very good points, mixing bins/spectrum to try and get overall higher PPFD/eff is a promise thats rarely met, what you get on the swings you lose on the merry go round. The matter of 'whiter' light is a whole other subject, google the black body locus and binning below and above the...

bro not sure what any of that means, 3500k diodes can be same diode count, cost to make is no different, longer life??? say what, cheers

I am yet to understand this. if you run 3000k and 4000k all your getting is 3500k, why not just run 3500k, phosphor converted light blends, if you want a specific CCT/Spectrum just buy that, I dont get why people think the sum of blending is greater than the whole of spectrum cheers

We use only the G class 2835 on 2790

Recently brought a Creality CR6 with touch screen and auto bed levelling for AUD399 shipped, its a cracking little printer, barely hear it, its so quiet just did a custom 4ft design, going to be putting these into the base of moulded trays for racking systems, Cree JB2835, 2700K, Lumileds 660...

I seem to recall the number was just PPF not PPF/W but it was a while ago and was likely at the 45ma base spec, not the 150ma max. My last GONI test from Teknik had a PC RED mixed with white at 2.1umol/j but it was at 44 watts so quite high. I think the PC red is in no way comparable to...

No problem dude share the word is never a bad thing

TOTALLY WRONG, there are not 2 companies in the world that make all led die, what you puffing dude:weed:
